Checking the differential gear oil level1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt and its gasket, and then check the oil lev-
el. It should be up to the brim of the filler
hole.
3. If the level is low, add sufficient oil of the
recommended type to raise it to the spec-
ified level. NOTICE: Be sure no foreign
material enters the differential gear
case.

Measure the spark plug gap with a wire thick-
ness gauge and, if necessary, adjust the gap
to specification.a. Spark plug gapInstallation1. Clean the surface of the spark plug gas- ket and its mating surface, and then wipe
off any grime from the spark plug
threads. 2. Install the spark plug and tighten it to the
specified torque. If a torque wrench is not
available when you are installing the
spark plug, a good estimate of the correct
torque is one-quarter to one-half turn
past finger tight. Have the spark plug
tightened to the specified torque as soon
as possible.
3. Install the spark plug cap.
4. Install the console.
Spark plug gap: 0.8–0.9 mm (0.031–0.035 in)
Tightening torque:Spark plug:
13 Nm (1.3 m·kgf, 9.4 ft·lbf)

2. Remove the tailpipe by pulling it out ofthe muffler, and then remove the gasket.
3. Tap the tailpipe lightly, and then use a
wire brush to remove any carbon depos-
its from the spark arrester portion of the
tailpipe and inside of the tailpipe housing.1. Tailpipe 2. Spark arrester 3. Gasket4. Install the gasket, and then insert thetailpipe into the muffler and align the bolt
holes.
5. Install the bolts and tighten them to the specified torque. Valve clearance
The correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a professional
Yamaha service technician.
